'To'all whom it may concerns t Y I I y Beit known thatl, 'Jaeon B. PDATT, of August-a, in thecounty ofltiehmond.and- State of Georgia, hare invented certain new anduseful Improvements in Machines for \Vashing and Separating Ores, Phosphates, and other llIiue'ral Substances .l'rom Clay and Other Earthy Matter and I do hereby declare .the following to be a fn'll,*clcai", and exaetdescription:of the same, reference-being had to; the accompanying drawing making a part of thisspecification, inwhichy l y Figure lnepresentsthe machine in perspective, with anopening broken thronghthe exterior cylinder, 7 toshow the rotary screen within it; I Figure'2 represents alongit-nd'imil vertical section throhghtbe sarne;fl i a V Figure 3 represents a vertical"transverse section through the elevating-conveyor;-and Fighre 4. representsja transverse section through theeylinder on jacket andro'tating 'serce n, within' it.

erated fromthe main drivingpower, and a carryingwheel, j, which revolvesiby the friction of the elevating orconveyor-chain, It, passing around both.

On this traveling endless chain are'scoops or buckets l l, which take up the washcd'and cleaned matc- The buckets '-l are perlbrated, to allow any. water .rcmaining'in the washed material to, drip or drain "uut, and"a screemjnrfis atlrangcd at the bottom-oi the conveyor-case G, covered by a hinged or swing ling .valve, n-',.throngh which, when necessary, the dirt or settlings may be drawn oil.

. When the a machine is at work theralve a should be closed, toiprevent the water from escaping-front the cylinder, as the washing is best done in a water, insteadt'oi against a flow of water, though a or current of water could be used in this mapool of flow chine; I prefer, however, to wash in a poolof water, and draw it off when neccssar to do-so, a
